Seeds growth

It may take you awhile to get any return on your seed investment.  The genus
you've picked are all notoriously slow germinators.  Here's the information I
could find on the subject.

Ilex:	Germination can take up to 3 years to complete, but may be improved by
warm stratification of alternating
	temps between 68 and 86 degrees Farenheit.

Juniperus:	The species J. ashei, J. deppeana, J. monosperma and J. virginiana
are recommended to be cold
		stratified at 41 degrees Farenheit for 30 to 120 days.  Below-freezing
temperatures during stratification
		may cause delayed germination, or even ruin the seeds.  Germination of J.
virginiana may be improved
		by soaking the seeds for 4 days in a 1 per cent solution of citric acid
before stratification.

Taxus:	Yews have a very strong dormancy, but it can be broken by warm and
cold stratification.  The recommendations
	I have read are 90 to 210 days at 60 degrees F., followed by 60 to 120 days
at 36 to 41 degrees F.  I have also
	read recommendations that specify prechilling the seeds for 270 days at 37
to 41 degrees prior to the above 
	warm-cold treatment.

Hope this helps.
